Create an encounter for a sample patient and navigate to the screen containing the chart item you wish to modify.

Write down the screen number that is associated with the list. This will be shown in the header of the Charting window. If a popup or content placeholder is currently being shown, then the screen number of both the parent form and the popup form will be shown (the popup screen code will appear in brackets after the description of the parent form, such as in the screenshot below)In this example, we are modifying an item in the "Modalities" popup window, which has a screen number of DC_HB_0200.03 shown in the screenshot above.
